New Delhi: City recorded 63.6mm rainfall in the last three days, making it in January annasited in the last 27 years.
Prior to this, Safdarjung, the weather station weather station, has received 69.8mm rainfall in January 1995.
Rain also cleanses the air with the air quality index (AQI) left in the “satisfying” category for 48 hours.
It was the first January to experience “satisfying” air day since the central pollution control board began to defend AQI from April 2015.
The two days of “satisfying” in January this year also made it rare.
Aqi was 91 on Saturday, which improved up to 69 on Sunday.
RK Jenamani, a senior scientist at the IMD, said, “Under the influence of the most active Western disorder this season, Delhi receives rain for two and a half days.
This Western disorder is unique because of the three factors – it remains for a longer period.
Above North Pakistan and The coexistent plain, the system vertical extension is stronger and extended to the top troposphere and picks very high humidity from the Arab Sea.
“Safdarjung recorded 5.4mm rainfall on Sunday between 8:30 am and 17:30.
Narella received the highest rainfall (12.1mm), while Lodhi Road Login 5.6mm.
Rain is now impossible until January 18.
Delhi records the lowest maximum temperature of the season at 15 degrees Celsius, four notches below normal.
The minimum temperature is completed at 13.8 degrees Celsius, seven degrees above normal.
“The day and night temperatures remain almost the same for 48 hours.
There are marginal differences in minimum and maximum temperatures due to Western disorders,” Jenamani said.
Gufran Beig, Director of the Founder Project, Safar, said.
“Because of the unprecedented rain in January, Aqi has been very low since Saturday.
Rarely that two-day satisfying consecutive is recorded in January.” Safar said, “From Monday, air pollutants may gradually accumulate in the air in the absence of rainfall and relatively moderate ventilation.
AQI is likely to be satisfying on Monday and decrease to moderate at low wind speeds.” Anumita Roychowdhury, Executive Director, Research and Advocacy, Science and Environmental Center, said, “Rain and increase wind speed washing pollutants.
We must see how pollution bounces back after the rain stops and cold conditions continue to win.”
